Answer:

y = 3x - 4

Step-by-step explanation:

Slope-intercept is defined y = mx + b

Where m = slope (change in y-coordinate/ change in x-coordinate)

and b = y-intercept (where the graph crosses the y-axis)

For every 1 unit the line moves horizontally... it travels 3 units vertically. Therefore the slope (m) equals 3/1 or 3

The line crosses the y-axis at -4. Therefore... the y-intercept (b) is -4

I hope this helps!

I got you. So first look for where the line crosses the y-axis which is the vertical line of the graph. This means the y-intercept is -4. Next you find the slope by counting the rise over the run. Which is 3/1 but it is just written as 3. Next we plug these into the slope-intercept form equation which is y=Mx+b. So the equation is y=3x-4
